Technical Field
[0001] The utility model relates to the technical field of hinges, in particular to a semi-embedded balance hinge. Background Art
[0002] A hinge, also known as a hinge joint, is a mechanical device used to connect two solids and allow relative rotation between the two. A semi-embedded balance hinge is one of the common hinges. The function of the semi-embedded balance hinge is to balance the weight of the door body, so that the door body can stay within a specific opening angle range. Part of the balance hinge is embedded in the device body, and the part protruding from the device body is less. When installing a semi-embedded balance hinge, generally, a part of the semi-embedded balance hinge is connected to the device body by bolts, and the other part of the semi-embedded balance hinge is connected to the door body by bolts. If it is necessary to remove the door body for maintenance of the door body and the device body, it is necessary to use tools to remove the bolts for connecting the door body and the semi-embedded balance hinge or the bolts for connecting the device body and the semi-embedded balance hinge one by one, which is time-consuming and laborious. Therefore, a semi-embedded balance hinge is proposed to facilitate the disassembly of the semi-embedded balance hinge. Summary of the Utility Model
[0003] Aiming at the problems in the prior art, the utility model provides a semi-embedded balance hinge.
[0004] The technical solution adopted by the utility model to solve its technical problems is a semi-embedded balance hinge, which includes a balance hinge body. A connecting block is provided at the bottom end of the balance hinge body. A fastening bolt is provided on one side of the connecting block. The connecting block is connected to the balance hinge body by the fastening bolt. A door body is provided above the balance hinge body. A plurality of connecting bolts are provided above the connecting block. The top end of the balance hinge body is connected to the door body by the plurality of connecting bolts. A device body is provided below the door body. Two receiving grooves for receiving the balance hinge body and the connecting block and four grooves are provided on the outer wall of the device body. An insertion block is provided in each groove. A guide rod is fixed on the side wall of each insertion block. A spring is sleeved on each guide rod. Four sliding grooves for the guide rods to slide are provided on the device body. A convex block is integrally formed on the side wall of each insertion block. Card slots adapted to the insertion blocks are provided on both sides of the connecting block.
[0005] By adopting the above technical solution, the insertion block, the guide rod and the spring cooperate to prevent the displacement of the connection block. If it is necessary to remove the door body, just push the convex block by hand. The convex block drives the insertion block to move away from the connection block. The spring is squeezed by the insertion block, and the insertion block disengages from the card slot on the side wall of the connection block, which facilitates the removal of the door body together with the balance hinge body. During installation, push the convex block, place the door body in its original position, place the connection block and the balance hinge body in the receiving groove, and then release the convex block. During the reset process of the spring, the spring pushes the insertion block to move towards the connection block, and the insertion block is inserted into the card slot on the side wall of the connection block, which facilitates the installation of the connection block, the balance hinge body and the door body. Only use tools to tighten the connection bolts and fastening bolts during the first installation. There is no need to use tools to loosen or tighten the connection bolts and fastening bolts during subsequent disassembly, which saves time and effort.
[0006] Specifically, an anti-slip pad is fixed to the side wall of each convex block away from the guide rod.
[0007] By adopting the above technical solution, the setting of the anti-slip pad facilitates the pushing of the convex block.
[0008] Specifically, decorative covers are provided in both of the receiving grooves, and the decorative covers are located on the side of the connection block away from the device body.
[0009] By adopting the above technical solution, the decorative cover can cover and protect the connection block, improving the aesthetic degree.
[0010] Specifically, four positioning columns are integrally formed on the side wall of each connection block, and four slots adapted to the positioning columns are provided on the side walls of the two decorative covers close to the connection block.
[0011] By adopting the above technical solution, the cooperation between the positioning columns and the slots on the side wall of the decorative cover facilitates the positioning and installation of the decorative cover.
[0012] Specifically, a protective cover is provided in each groove, and each protective cover is rotatably connected to the device body.
[0013] By adopting the above technical solution, the setting of the protective cover can cover and protect the insertion block, the guide rod and the spring.
